According to this article on Slate Magazine's website yes http://www.slate.com/id/2211158/?GT1=38002 but I disagree. Satellites have a wider coverage than 3G cellular internet or WIFI and this is by no means a new technology, it all started in the late 1980s when a satellite enthusiast proposed to the FCC to allocate some spectrum for the idea and to an extent it has made terrestrial AM and FM broadcasts endangered because of ad free music channels with real DJs on the air most of the time and also music that cannot be heard on terrestrial radio along with talk personalities exclusive to satellite and nationwide sports coverage. I personally own a Sirius/XM receiver and very much enjoy the wide variety of music and talk that satellite radio has to offer. These are my thoughts on the issue but what do you think. Is satellite radio really endangered because of mobile internet access or is it here to stay?
